Cotton cloth bag is a kind of environmental protection cloth bag. It is a daily necessities. It is small, convenient, durable and does not pollute the environment. Cotton cloth bag is also a kind of environmental protection bag, and this type is delicate, convenient, durable, can be degraded in the natural environment, and will not pollute the environment. Of course, its advantage is that it can be reused many times and is more durable than ordinary environmental protection bags. What are the characteristics of cotton bags?
What are the characteristics of cotton bags?
1. Heat resistance: pure cotton fabric has very good heat resistance. When the temperature is below 110, it will cause water transpiration to the fabric and will not damage the fiber together. Therefore, pure cotton fabrics are worn and used at normal temperature.
2. Cleanliness: the raw material of cotton cloth is natural fiber, and the main component is cellulose. Of course, there are a small amount of waxy substances, nitrogen-containing substances and pectin. The cleanliness is relatively good.
3. Hygroscopicity: the environmental protection bag made of cotton has excellent hygroscopicity. This fiber can absorb water into the surrounding atmosphere, with a water content of 8-10%, so it feels soft but not stiff when it comes into contact with human skin.
4. Moisture retention: cotton fiber is a poor conductor of heat and electricity, with extremely low thermal conductivity. Besides, cotton fiber itself has porosity. For example, that fiber can store a lot of air. Basically, air is a poor conductor of heat and electricity. Therefore, pure cotton fiber textiles have good moisture retention.
